Sterile Water for Injection, USP
Sterile Water for Injection, USP is a sterile, nonpyrogenic water for injection intended only for dilution purposes. The pH is 5.4 (5.0 to 7.0). The Pharmacy Bulk Package is a sterile dosage form which contains multiple single doses for use only in a pharmacy bulk admixture program.
Sterile Water for Injection, USP contains no bacteriostat, antimicrobial agent or added buffer.
Sterile Water for Injection, USP may be classified as a sterile diluent and pharmaceutical vehicle.
Sterile Water for Injection, USP is chemically designated H2O.
The flexible plastic container is fabricated from a specially formulated polyvinylchloride. Water can permeate from inside the container into the overwrap but not in amounts sufficient to affect the solution significantly. Solutions inside the plastic container also can leach out certain of its chemical components in very small amounts before the expiration period is attained. However, the safety of the plastic has been confirmed by tests in animals according to USP biological standards for plastic containers.
Water is an essential constituent of all body tissues and accounts for approximately 70% of total body weight. Average normal adult daily requirement ranges from two to three liters (1.0 to 1.5 liters each for insensible water loss by perspiration and urine production).
Water balance is maintained by various regulatory mechanisms. Water distribution depends primarily on the concentration of electrolytes in the body compartments and sodium (Na+) plays a major role in maintaining physiologic equilibrium.
INDICATIONS AND USAGE
Sterile Water for Injection, USP in the Pharmacy Bulk Package is indicated for use with automated compounding devices for preparing intravenous admixtures in the pharmacy.
FOR DILUTION ONLY.
Do not heat over 66°C (150°F).
This preparation is solute-free and its entry into the circulation undiluted will cause hemolysis.
Absorption of large amounts of Sterile Water for Injection, USP with additives can cause fluid and/or solute overloading resulting in dilution of serum electrolyte concentrations, overhydration, congested states or pulmonary edema. The risk of dilutional states is inversely proportional to the electrolyte concentrations of administered solutions. The risk of solute overload causing congested states with peripheral and pulmonary edema is directly proportional to the electrolyte concentrations of such solutions.
WARNING: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.
Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.
Do not use unless water is clear, seal is intact and container is undamaged.
Aseptic technique is essential with the use of sterile preparations for compounding admixtures.
Discard container within 4 hours of entering closure.
Accidental contamination from careless technique may transmit infection.
Should any adverse reaction occur, evaluate the patient, institute appropriate therapeutic countermeasures and save the remainder of the fluid for examination, if deemed necessary.
DOSAGE AND ADMINISTRATION
Sterile Water for Injection, USP in the 2000 mL flexible Pharmacy Bulk Package is designed for use with automated compounding devices for preparing intravenous admixtures. Dosages will be in accordance with the recommendation of the prescribing physician.
Sterile Water for Injection, USP is not intended for direct infusion. Admixtures should be made by or under the direction of a pharmacist using strict aseptic technique under a laminar flow hood. Compounded admixtures may be stored under refrigeration for up to 24 hours. Administration of admixtures should be completed within 24 hours after removal from refrigeration.
The Pharmacy Bulk Package is intended only for use in the preparation of sterile, intravenous admixtures using automated compounding devices.
Additives may be incompatible with the fluid withdrawn from this container. Consult with pharmacist, if available. When compounding admixtures, use aseptic technique, mix thoroughly and do not store.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution container permits. See PRECAUTIONS.
Some opacity of the plastic due to moisture absorption during the sterilization process may be observed. This is normal and does not affect the solution quality or safety. The opacity will diminish gradually.
